	<span lang=\"EN-US\" style=\"font-family:Verdana;\">It is shown that aplanatic lens with a radial gradient
of refraction index is simultaneously a telescopic lens, notably not only for
an axial beam, but also for an off axis parallel beam. Consideration is carried
out by an algebraic way on the basis of regularities of ray paths. It is also
shown that aplanatic and telescopic properties of the lens are independent of
the refracting surface shapes. Various versions of lens performance are shown
below.</span>
